+ * Ensure extension-specific packages are resolvable from shared dist/ chunks.

+ * OpenClaw's Rollup bundler creates shared chunks in dist/ (e.g.
+ * sticker-cache-*.js) that eagerly `import "grammy"`.  ESM bare specifier
+ * resolution walks from the importing file's directory upward:
+ *   dist/node_modules/ → openclaw/node_modules/ → …
+ * It does NOT search `dist/extensions/telegram/node_modules/`.
+ *
+ * NODE_PATH only works for CJS require(), NOT for ESM import statements.
+ *
+ * Fix: create symlinks in openclaw/node_modules/ pointing to packages in
+ * dist/extensions/<ext>/node_modules/.  This makes the standard ESM
+ * resolution algorithm find them.  Skip-if-exists avoids overwriting
+ * openclaw's own deps (they take priority).
